The (Northern) Sporades (/ˈspɒrədiːz/; Greek: Βόρειες Σποράδες, Vóries Sporádhes [ˈvories spoˈraðes]) are an archipelago along the east coast of Greece, northeast of the island of Euboea,^[1] in the Aegean Sea. They consist of 24 islands, four of which are permanently inhabited: Alonnisos, Skiathos, Skopelos and Skyros.^[1] They may also be referred to as the Thessalian Sporades (Θεσσαλικές Σποράδες).

"Sporades" means "those scattered" (compare with "sporadic"). From Classical Antiquity the name has referred to the Aegean island groups outside the central archipelago of the Cyclades.

In modern geographical parlance, there are five different Sporades groups:

• Thessalian Sporades (Θεσσαλικές Σποράδες) or Northern Sporades. Since c. 1960, the term "Sporades" refers mainly to these islands:
  • Skopelos
  • Alonnisos
  • Skiathos
  • Skyros
  • Kyra Panagia
  • Peristera
  • Gioura
  • Skantzoura
  • Piperi
  • Tsougria
• Thracian Sporades (Θρακικές Σποράδες): Thasos, Samothrace, Imbros, Lemnos and Agios Efstratios
• Western Sporades (Δυτικές Σποράδες): Salamis, Aigina, Poros, Hydra, Spetses, and the other islands of the Saronic Gulf and the Myrtoan Sea.
• Eastern Sporades (Ανατολικές Σποράδες), i.e. the islands of the eastern and northeastern Aegean, near the coast of Asia Minor: Samos, Ikaria, Lesbos, Chios, Tenedos, Psara, Oinousses and smaller island groups
• Southern Sporades (Νότιες Σποράδες), i.e. the Dodecanese, to which group Samos and Ikaria are sometimes appended.

As part of the 2011 Kallikratis government reform, the Sporades Regional Unit (Περιφερειακή Ενότητα Σποράδων) was created out of part of the former Magnesia Prefecture, region of Thessaly. The regional unit is subdivided into 3 municipalities. These are:^[2]

• Skiathos (1)
• Skopelos (3)
• Alonnisos (2)

The island of Skyros and a few uninhabited islets in its area are part of the Euboea regional unit and the administrative region of Central Greece.
